Filed: 1987-08-10
Abstract: PURPOSE:To prevent an overcharging accident from occurring by generating an alarm when the feedback voltage of a vehicle battery is predetermined voltage or more lower than the feedback voltage of an output voltage. CONSTITUTION:If an improper contact at a C terminal or an insulation deterioration of a voltage dividing line for obtaining a feedback voltage VF1 of a battery 1 occurs, the voltage VF1 gradually drops in response thereto, and the voltage FF1 reduces lower than the feedback voltage VF2 of the output voltage FA of a charging generator 3 even in a nongenerating state of the generator 3.
